After weeks of testing the strips we found that there was not a lot of change with the weight and the average tinsel strength was about 15 pounds. We found that the strips did not decompose as much as we hoped they would.
Team 2:
Scott, David, Townes, Max
Environment: Open, Moist, Soil
After the 14 weeks of doing this project we were quite upset with the results. The PSI that it took to tear the strips stayed on average at between 15 and 20 PSI. When the weight was effected it was only by about .1 grams or so.

Environment: water
After staying in water the strips of bag decomposed a little, but for the most part just split into two different strips. One of the new strips was just a clear material and the other was the colored layer from the outside of the bag. This splitting of the strips made our data inconsistent. Week 11 was much stronger and heavier than week 10 because the week 11 strip had not split yet. Throughout the experiment the strips did get weaker and lighter but that was mainly from the splitting. Overall, water would not be a successful compost for the sun chip bag.
